Dick, I'm certain you know more about tips than I do, but I occasionally use a Willard shaper very gently on my Moori soft tip. Just a trace of debris comes off. I've been using the same tip for over a year and haven't had any hardening, mushrooming or glazing over. There's still quite a bit of tip left. I just recently bought a Forever Tool and really like it.
Do you say not to use a shaper because of wear? I would assume the tip flattens slightly after much use and would not have a perfect dime diameter. By the way, I have a tip pick but do not use it because I don't like it. I'm not a cue maker but read this part of the forum just for education.
